AMD Radeon Pro Vega 20 vs Intel Arc Pro A30M Comparison

Where Each One Wins

The recorded data gives a clear, if narrow, competitive picture. The Intel Arc Pro A30M wins the only shared benchmark test, Geekbench OpenCL, with a decisive 19.5% lead over the AMD Radeon Pro Vega 20. That is the sole head-to-head comparison in the database, so the Intel part takes the overall win count at 1 to 0. However, the AMD Radeon Pro Vega 20 has its own recorded strengths in other API tests that the Intel part does not have on file. Specifically, the AMD card posts a Geekbench Metal score of 30427 and a Geekbench Vulkan score of 26410. The Intel Arc Pro A30M has no Metal or Vulkan benchmark entries in the database, so those workloads represent an area where the AMD part is the only one with verified performance data. In practical terms, the Intel Arc Pro A30M is the stronger choice for OpenCL compute tasks, while the AMD Radeon Pro Vega 20 has demonstrated capability in Apple-centric Metal workloads and Vulkan applications, based on the available measurements.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The Intel Arc Pro A30M is built on the Xe-HPG architecture, specifically the DG2-128 chip, and belongs to the Alchemist (Pro-Series Mobile) generation. It is fabricated on a 6 nm process at TSMC, with 7,200 million transistors packed into a 157 mm² die, yielding a transistor density of 45.9 million per square millimeter. The AMD Radeon Pro Vega 20 uses the older GCN 5.0 architecture with the Vega 12 chip, part of the Radeon Pro Mac (Vega Series) generation. It is built on a 14 nm process at GlobalFoundries, and the database does not list transistor count, die size, or density for this part. The process node difference is substantial, with the Intel chip using a more advanced 6 nm node compared to the AMD chip's 14 nm node.

Clock behavior also differs sharply. The Intel Arc Pro A30M runs at a 1500 MHz base clock and boosts to 2000 MHz, while the AMD Radeon Pro Vega 20 has a much lower 815 MHz base and 1283 MHz boost. Despite the lower clocks, the AMD part has more shading units (1280 versus 1024), more texture mapping units (80 versus 64), and the same number of ROPs (32). The Intel part has 8 dedicated ray tracing cores, while the AMD part has none listed. Memory architecture is another major divergence: the Intel card uses 4 GB of GDDR6 on a 64-bit bus with 128.0 GB/s bandwidth and 16 Gbps effective speed, while the AMD card uses 4 GB of HBM2 on a 1024-bit bus with 189.4 GB/s bandwidth and 1480 Mbps effective speed. The AMD part's wider bus and HBM2 technology give it significantly higher memory bandwidth despite the lower memory clock.

The bus interface also differs: the Intel part uses PCIe 4.0 x8, while the AMD part uses PCIe 3.0 x16. The AMD part is classified as an IGP (integrated graphics processor) with a slot width of "IGP", whereas the Intel part has no slot width listed. Power consumption is notably different, with the Intel part rated at 50 W TDP and the AMD part at 100 W TDP. API support shows a generational gap: the Intel part supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the AMD part supports DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6.

Head-to-Head Benchmarks

The only direct comparison available is Geekbench OpenCL, and the results strongly favor the Intel Arc Pro A30M. The Intel part scores 31894, while the AMD Radeon Pro Vega 20 scores 26679. That is a 19.5% advantage for Intel, a substantial margin in a compute benchmark. To put the Intel score in context, its nearest rivals in the database include the NVIDIA TITAN RTX at 31676 (a 0.7% delta, meaning Intel is slightly ahead), the AMD Radeon Pro 570X at 32176 (Intel is 0.9% behind), the NVIDIA RTX PRO 4500 Blackwell at 31532 (Intel is 1.1% ahead), and the AMD FirePro S10000 at 32388 (Intel is 1.5% behind). This places the Intel Arc Pro A30M in a tight cluster around the 31,500 to 32,400 range, competing with much larger desktop cards. Its percentile ranking among all GPUs is 76.

The AMD Radeon Pro Vega 20, by contrast, has an average benchmark score of 27839 across all its recorded tests (Metal, OpenCL, Vulkan), and a percentile ranking of 73. In OpenCL specifically, it sits well below the Intel part. Its nearest rivals are the AMD Radeon RX 7800M at 27883 (a 0.2% delta, AMD is slightly behind its rival), the AMD Radeon Pro W5500X at 27973 (0.5% behind), the NVIDIA GeForce GTX 980 Ti at 28020 (0.6% behind), and the NVIDIA GeForce RTX 3090 at 27565 (AMD is 1% ahead). These deltas show that the AMD Radeon Pro Vega 20's average score is essentially on par with a range of very different GPUs, from a modern mobile Radeon to a 2015-era GeForce flagship. The Intel part, by comparison, punches near the level of a TITAN-class card in OpenCL, which is notable for a 50 W mobile GPU.
